METHOD AND SYSTEM FOR TRANSMITTING DOWNLINK CONTROL INFORMATION Russian patent published in 2014 - IPC H04B7/26 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to mobile wireless communication. When a base station is not configured with a carrier indicator field, the base station transmits a physical downlink control channel bearing the corresponding downlink control information on each downlink component carrier in a user equipment's physical downlink shared channel (PDSCH) carrier set, and the user equipment detects the corresponding downlink control information on each downlink component carrier in the configured PDSCH carrier set. When a base station is configured with a carrier indicator field, the base station transmits the physical downlink control channel bearing the corresponding downlink control information on each downlink component carrier in the configured physical downlink control channel (PDCCH) carrier set, and the user equipment detects the corresponding downlink control information on each downlink component carrier in the PDCCH carrier set.

EFFECT: invention can prevent multiple blind detection and can facilitate transmission and detection of downlink control information with multiple carriers.
